IMPROVEMENT lN PORTABLE FENCES Specification forming part of Letters Patent No. i lflm dated September 3, 1872.

SPECIFICATION.

Be it known that I, J A0013 HOFFMAN, of the town of Hinton, in the county of Jackson and in the State of Wisconsin, have invented an Improved Self-Brace Movable Fence; and do hereby declare that the following description, taken in connection with the accompanying plate of drawing hereinafter referred to, forms a full and exact specification of the same, wherein I have set forth the nature and principles of my said improvement, by which my invention may be distinguished from others of a similar class, together with such parts as I claim and desire to secure by Letters Patent.

My invention relates to improvements in fences; and the nature thereof consists in the construction and arrangement of the parts thereof, hereinafter shown and described.

In the accompanying plate of drawing, which illustrates my invention and forms a part of the specification thereof. corresponding parts being designated by similar letters Figure l is a perspective view. Fig. 2 illustrates a detached section of fence.

The construction and relative arrangement of the component parts of my invention are as follows: Each section of the fence-is composed of three rails, A B O, and three posts, D E F. On either end of the said rails are wrought the diagonal notches d e f, and the projections d e f, fitting exactly within the same in such a manner as to form a lock-joint, and fasten the sections of the fence in such a manner as to resist extraneous pressure, and to prevent one section of the fence from being lifted from the other. The end posts 1) and F are provided with the hasps a a and staples b b. Over the lower hasp a, and at each angle of the fence, are driven the notched stakes H, which hold the fence firmly in position and prevent it from being overthrown.

Having thus described the construction and operation of my invention, I will state wliat I claim, and desire to secure by Letters Patent, in the following clause:

I claim the rails A B 0, having their ends formed with the diagonal notches d c f and projections 61 e f, so as to make a lock-joint, as specified, in combination with the posts, hasps, staples, and notched stakes H, as shown and described.

In testimony that I claim the foregoing I have hereunto set my hand and seal this 29th day of May, 1871.
